Benefits of technology

The present invention aims to offer a steering column for automobiles that is easy to use and manufacture. The existing issues that previously existed with conventional steering columns have been addressed by this invention. The technical effects of this patent are a simplified and cost-effective steering column for automobiles that is free from previous drawbacks.

Problems solved by technology

The steering columns of the aforesaid known type have some drawbacks mainly deriving from the fact that the release crank can be only manually operated by the operator, and not also by means of an operating pedal coupled to the release crank through a traction cable like, for example, a Bowden cable.

Embodiment Construction

[0019]With reference to FIGS. 1 and 2, number 1 indicates, as a whole, a steering column for vehicles comprising a lower shaft 2 adapted to be connected to a chassis (not shown) of a vehicle (not shown) by interposing a coupling plate 3. The shaft 2 has a longitudinal axis 4 and is slidingly engaged by an intermediate shaft 5, which is coaxial to the axis 4, has a tubular shape and extends around the shaft 2. The steering column 1 further comprises an upper shaft 6 rotatably coupled to the shaft 5 to rotate, with respect to the shaft 5, around a rotation axis 7 transverse to the axis 4.

[0020]As shown in FIG. 3, the steering column 1 has a drive shaft 8 which extends through the shafts 2, 5, 6, and comprises a bottom portion 9, an intermediate portion 10 and an upper portion 11 which are rotatably and axially fixed engaged to the shafts 2, 5, and, respectively, 6.

[0021]The portion 11 has an upper free end projecting outside the shaft 6 for housing and holding a steering wheel (not sh...

Abstract

A steering column for vehicles has an intermediate shaft, slidingly coupled to a lower shaft connectable with a chassis of a vehicle and rotatably coupled to an upper shaft connectable with a steering wheel of the vehicle, two locking devices to lock the intermediate shaft and, respectively, the upper shaft, and a release crank mounted to move in sequence in a release position of the locking device of the upper shaft and in a release position of the locking device of the intermediate shaft with a movement in a single forward direction.

Description

[0001]The present invention relates to a steering column for vehicles.[0002]In particular, the present invention relates to a steering column for vehicles of the type comprising a lower shaft configured to be connected to a chassis of a vehicle; an intermediate shaft, slidingly coupled to the lower shaft to move along a longitudinal axis of the lower shaft; and an upper shaft, which supports a steering wheel of the vehicle and is rotatably coupled to the intermediate shaft to rotate around a rotation axis.[0003]The steering column further comprises a first locking device to lock the intermediate shaft along said longitudinal axis; and a second locking device to lock the upper shaft about said rotation axis.[0004]Generally, the first locking device comprises a braking member, which is carried by the intermediate shaft and is mobile between a locking position and a release position of the lower shaft.[0005]The second locking device usually comprises a first and a second toothed sector...
